Recently, research has been actively conducted for getting interested in unit module housing. However, the domestic unit modular housing research in the early stages yet, so the major process for research is lacking. Explore all these reasons fit with domestic unit housing development this paper, focusing on the process of shipping cargo by truck, transport unit module was studied. The purpose of this paper is to present new ideas and derive the direction of the development of the equipment safely and effectively fixed to the unit module of the transport unit module that will be helpful in the development of the equipment required for the transport process of the next unit module.

The unit modular system is a type of prefabricated construction method that completes the building by uniting the modular units on site by transporting the unit module structure manufactured in the factory to the site. Since the unit module structure is not only the frame but also the finished form including the inner and outer materials, it is most likely to be brought into the field. Therefore, not only the damage of the inner and outer materials but also deformation of frame structure due to the vibration generated during the transportation of the vehicle, And it is necessary to take appropriate methods when transporting the module structure. However, there are no methods to prevent modular structure damage due to vehicle vibration in domestic and foreign modular transportation guidelines or standards. In this study, we investigate the vibrations during the vehicle transportation of the module structure through the road driving test, identify the vibration frequency characteristics of the vehicle through FFT analysis, and propose a vibration reduction methods for module transportation.

In this study, focusing on work types of lifting modules and modules assembly in modular construction sites, unit works were defined according to the construction process of each work type, and safety management elements, safety management activities, and key check point were proposed. The results of this study may have somewhat overlapping contents in the construction procedure in order to derive specific safety management activities and check point for each unit work. Therefore, there is a limit to use the results in an actual modular construction site. In future research, we plan to improve this part and derive a checklist that considers field usability.

모듈러 공법은 전체공정의 50%~90%를 공장에서 제작하여 이를 운반하여 현장에서 설치하는 공법이다. 이 공법은 현장에서 공정을 최소화하고 공장에서 작업을 극대화하여 공기를 단축하고 품질을 향상시킬 수 있다. 모듈러 공법으로 시공하면, 사용연한이 지나 건축물 철거시 일부 또는 전체를 재사용이 가능하기 때문에 건축폐기물까지 줄일 수 있는 친환경적인 공법이라고 할 수 있다. 이 모듈러 공법은 최근 수요가 증가하는 소형주택과 한국전쟁 당시 지어진 전방의 노후화된 병영시설의 교체에 적합한 공법이다. 경량철골을 사용한 모듈러 공법의 국내 시공 사례는 2003년 신기초등학교를 시작으로 군 병영시설에 확대 적용되고 있지만 아직까지 시장 초기단계이다. 따라서 범용 적으로 활용이 가능한 모듈 유닛의 표준과 공정의 표준정립이 시급한 상태이다. 본 연구에서는 기존 독신숙소의 신축 사례를 바탕으로 1인 숙소를 표준 모듈로 가정하고 모듈의 공장제작, 운반, 현장설치의 모듈러 공법의 최단 공사기간내의 최소 공사비 투입이 가능한 표준 공정을 제안하고자 한다. 공장에서 완성품을 제작하는 것이 가장 합리적이지만 운반시 하자발생을 감안한다면 공장제작비율 80%일 때 가장 합리적인 것으로 도출 되었다.

The unit modular method is one in which unit modules are prefabricated at a factory and then constructed at a construction site. That is why an important process, transporting unit module, is added in this method. The purpose of this study is to analyse the load for transporting unit module. The results of the analysis of the driving experimental runs revealed that a maximum load of 15 kN was applied on adapter block type A and a maximum load of 25 kN on adapter block type B. These loads were recorded at the points in the road test when the low-bed trailer was driving through unstable sections of the test such as stopping, restarting, passing over a speed bump or taking a left turn at speed.

Recent research has been ongoing for modular buildings in the country, and interest increases. However, in accordance with legal restrictions in the country with regard to Project Delivery system of Modular Building, the activation of modular buildings industry is obstructed. In Korea, in accordance with national contract law, the construction contract is apply to the project delivery system of modular buildings, and in accordance with Framework Act on the Construction Industry, The project delivery system of modular buildings has to be a separate order. The definition of separate order in contract as defined in the law is that the electric work and Communication work and digestion facility work has to be separate each contract in order to be ensured professionalism. In accordance with law, the project delivery system of modular buildings is that the contract for construction is concluded with the Owner and the Construction Contractor and the contract for goods is concluded with the construction Contractor and modular manufacturer. Due to these project delivery system, the domestic factory production rate when making a modular unit is significantly reduced compared to the rate of factory production abroad and the domestic factory production rate is estimated to 10-20%. Due to the factory production rate is also low, despite what can be done at the factory the workload in construction field increases. According to the workload in field increases, the effect of the schedule reduction can be reduced. It resolved to form a consortium with a modular manufacturer and construction companies or the contract is concluded with Owner, modular manufacturer and construction companies in each. In this paper, we propose a specific project delivery system for modular building to solve the problem of the low factory production rate and the problem of schedule reduction. Through this paper, due to the variety of project delivery system on modular buildings is expected to contribute to the activation of modular buildings.

A modular house is a house that is assembled on-site from modularized units. As such units are manufactured in a factory, the construction period is reduced, resources are recycled, and quality is improved. However, the construction technique applied to conventional modular houses has not overcome certain structural restrictions, as it is currently used to build houses less than 4 stories in height, which means that it lacks economic feasibility. For this reason, this research aims to develop a scenario of a construction method for Korean modular housing that can be applied to urban-type housing higher than 12 stories. This research is expected to provide fundamental data necessary for the future development of a construction method for Korean modular housing.

The productivity of the construction industry is lower than other industries. Modular system is suggested to enhance the productivity of the construction industry. Modular system is a construction method which installs units manufactured in factory on site. It enables to reduce the duration and improve the quality of the constructions. However, the construction technique applied to modular system has not overcome certain structural problems. To solve the problems and motivate the application of modular system, this study propose the hybrid system which use core to resist a lateral force.
